Note: Specific composition depends on supplier blend; all substances listed above play a role in end-use performance
Inhalation: If dust generated, move to fresh air, rinse mouth, seek medical help if symptoms develop
Skin Contact: Wash with soap and warm water; remove contaminated clothing, treat irritation if present
Eye Contact: Rinse with clean water for at least 15 minutes, remove contact lenses if present, seek attention if stinging persists
Ingestion: If swallowed, rinse out mouth, do not induce vomiting, call doctor if large amounts are involved
Burns (in case of molten product): Cool burn area with water, do not remove solidified resin, seek medical attention
Suitable Extinguishing Media: Foam, water mist, dry chemical, carbon dioxide
Unsuitable Extinguishing Media: Direct water jets on burning plastic may cause spreading
Specific Hazards: Combustion releases toxic gases like HBr, CO, CO2, and antimony compounds
Protective Gear: Full turnout gear including self-contained breathing apparatus
Advice for Firefighters: Keep containers cool with water, control runoff, evacuate area if large fire
Personal Precautions: Wear gloves, goggles, dust protection in case of spills involving powder
Environmental Precautions: Prevent pellets or powders from washing to drains, waterways
Cleanup Methods: Shovel or sweep up and place in suitable container for reuse or disposal
Reference to Other Sections: Use handling and disposal recommendations to avoid environmental release
Secondary Containment: Use absorbents for melted or decomposed product
Handling: Avoid dust formation, use local exhaust if processing produces shavings or fumes, don’t eat or drink near open handling, wash hands after use
Protective Measures: Wear gloves and goggles, especially during machine feeding or cleaning
Safe Storage: Store in cool, dry, well-ventilated area; away from direct sunlight, open flames, strong oxidizers
Incompatible Materials: Avoid mixing with acids, oxidizers, strong bases
Occupational Exposure Limits: Antimony Trioxide: OSHA PEL 0.5 mg/m³; Brominated Compounds: No established U.S. PEL, follow manufacturer guidance
Engineering Controls: Provide local ventilation at points where dust or fumes may be generated
Personal Protective Equipment (PPE): Safety goggles, gloves, long sleeves, dust mask or respirator for dusty conditions, closed footwear
Hygienic Practices: Wash hands after use; shower and change before leaving workplace if significant exposure involved
Respiratory Protection: Use NIOSH-approved masks if dust concentration exceeds guidelines
Appearance: White to off-white pellet or granule
Odor: Slight plastic-like odor
Melting Point: 220–250°C (dependent on base PC resin)
Boiling Point: Not applicable
Flash Point: Above 350°C for base PC
Solubility: Insoluble in water
Vapor Pressure: Not relevant for solid
Density: 1.10–1.35 g/cm³
Autoignition Temperature: Approx. 500°C
Decomposition Temperature: Above 300°C
Chemical Stability: Stable at ambient temperature and pressure during normal use
Thermal Decomposition: Produces HBr, CO, CO2, antimony fumes if significantly overheated
Hazardous Reactions: Contact with strong alkalis, acids, or strong oxidizers can initiate breakdown
Polymerization: Not expected
Conditions to Avoid: Prolonged or excessive heat, incompatibles, open flames
Acute Toxicity: Finished pellets show low toxicity by oral, dermal, inhalation routes; Dust or fumes increase risk
Chronic Exposure: Prolonged inhalation of antimony trioxide dust linked to lung effects; some brominated compounds flagged by regulatory agencies for persistent toxicity
Skin and Eye Contact: Minor irritation possible from processing dust but no sensitization documented
Carcinogenicity: IARC lists antimony trioxide as Group 2B (possible human carcinogen); base polycarbonate is not a carcinogen
Other Effects: Chronic exposure to dust should be avoided by routine hygiene and PPE
Environmental Fate: Pellets are persistent in land and aquatic environments, unlikely to degrade rapidly
Aquatic Toxicity: Additive leaching can impact fish or invertebrates if exposed to large quantities
Mobility: Solid form remains in soil or sediment; powder can be carried in surface water
Bioaccumulation: Some flame retardants can build up in organisms over time
Waste Minimization: Cleanup spills promptly, minimize dust generation, avoid release outside facilities
Waste Treatment: Collect unused pellets and powder for approved landfill or incineration; consult local authorities
Recycling: Recycle scrap whenever feasible—contact authorized processor handling halogenated additives
Coding: Use waste codes appropriate to brominated waste or “Plastic Scrap—Containing Additives”
Precautionary Measures: Don’t allow uncontrolled discharge to soil, drains, surface water
Container Disposal: Triple rinse or remove product, recycle or dispose according to local regulations
UN Number: Not regulated as dangerous goods under UN, ADR, IATA, IMDG
Packaging: Use sealed bags or drums to avoid dust emission, pallets for bulk shipment
Special Shipping Instructions: Prevent pellet or powder loss during handling
Hazards During Transport: No special hazards for finished product; avoid loading near strong oxidizers or food cargo
Classification: Not classified as hazardous for transportation in most jurisdictions
TSCA Status: All components listed or exempt
REACH Status: Additive registration relevant in Europe; supplier provides compliance confirmation
OSHA: Some additives subject to workplace monitoring requirements
US SARA Title III: Certain flame retardants and antimony compounds appear on reporting lists
Other Listings: California Proposition 65 warning for exposure to antimony trioxide and some brominated compounds; check label and SDS updates regularly
